This will loop infinitely.

There are two types of incrementing a variable:

Here <code>count++</code> and <code>++count</code> both are different if you have used <code>++count</code> it will work.

Here <code>count = count++</code> means count variable will be incremented by one then assigns the earlier value 1 to the count variable itself so count remains unchanged.

The expression <code>count++</code> returns the original value of count, then increments the value afterwards.

So you are overwriting count with the same value every time. Just do this:

<pre><code>count++;
</code></pre>

For the curious, here's a link to Eric Lippert's article which distinguishes between operator precedence and the order of evaluation -- it's an interesting read:

blocks|key|998981|text|count++=+count%2B%2B;不会将count递增1。x%2B%2B是后增量运算符，这意味着表达式返回的值是旧值。因此，在您的代码中，会发生以下情况：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|998982|int+oldValue+=+count;

<code>count = count++;</code> does not increment <code>count</code> by one. <code>x++</code> is the post increment operator, which means that the value returned by the expression is the old value. Thus, in your code, the following happens:

<pre><code>int oldValue = count;
count = count + 1;
count = oldValue;
</code></pre>

What you probably meant to write was <code>count++;</code> (without the "<code>count =</code>").

More details about this can be found in the following SO question:

The ++ operator first saves the current value then increments and finally returns the saved value, so <code>count</code> will never change.

Eiter use the <code>++</code> operator or do an assignment. These are all equivalent:

<pre><code>count++;
count += 1;
count = count + 1;
</code></pre>

<pre><code>count = count++;
</code></pre>

This is a post-increment. It does the following.

<pre><code>int temp = count;
count++;
count = temp;
</code></pre>

So you're not incrementing count. Use the following instead:

<pre><code>while (count &lt; 10)
{
 ++count;
}

because

returns <code>count</code>, not <code>count + 1</code>

just have count++ with no assignment or:

<pre><code>count = ++count;

the last one only to explain but you should not use it...

from: <a href="http://msdn.microsoft.com/en-us/library/36x43w8w.aspx" rel="nofollow">++ Operator (C# Reference)</a>

<blockquote>
 The first form is a prefix increment operation. The result of the
 operation is the value of the operand after it has been incremented.
 
 The second form is a postfix increment operation. The result of the
 operation is the value of the operand before it has been incremented.
 
 Numeric and enumeration types have predefined increment operators.
 User-defined types can overload the ++ operator. Operations on
 integral types are generally allowed on enumeration.

It is infinite because you aren't actually incrementing count.

count = count++; assigns the value of 1 to count and then increments count but since you don't assign the incremented value count never increases.

You need to do either:

<pre><code>count++;
</code></pre>

or

<pre><code>count = ++count;
</code></pre>

blocks|key|999133|text|让我问你一个问题，为什么你在一个变量上做两个操作，而一个操作就足够了？你的意图是什么？count%2B%2B本身就足够了，所以为什么还要赋值给count。也许你想做些别的事情。你可以只使用count%2B%2B，或者%2B%2Bcount或者count%2B1。我认为其他的方式会导致两种操作。很抱歉我的写作方式。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|999134|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Let me ask you a question why do you make two operations on a single variable while one is enough?
what was your intention? count++ itself was enough so why again assign to count. May be you want to do something else.
You could have only count++, or ++count or count+1. I think other ways causes two operations.
Sorry for my way of writing.

This is a simple while loop in C# but it is working infinitely.

<pre><code>int count = 1;
while (count &lt; 10)
{
 count = count++;
}
</code></pre>

Why is this so?
